I think with the hybrid defenses being thrown out there right now, centers become more valuable as line calls become more important.
This would seem to mean that Centers have to be smarter, not necessarily better physically. Maybe that's why it looks like they want to go with a guy from Cornell who scored 30+ on the Wonderlic.
Ring the bells that still can ring
Forget your perfect offering
There is a crack, a crack in everything
